Jack Harkness

Captain Jack Harkness is a fictional character played by John Barrowman in ''Doctor Who'' and its spin-off series, ''Torchwood''. The character first appears in the 2005 ''Doctor Who'' episode "The Empty Child" and subsequently features in the remaining episodes of the first series (2005) as a companion to the series' protagonist, the Doctor. Subsequent to this, Jack became the central character in the adult-themed ''Torchwood'', which aired from 2006 to 2011. Barrowman reprised the role for appearances in ''Doctor Who'' in its third, fourth, and twelfth series, as well as specials "The End of Time", and "Revolution of the Daleks".

In contrast to The Doctor, Jack is more of a conventional action hero, as well as outwardly flirtatious and capable of acts which The Doctor would view as less than noble. In the programme's narrative, Jack begins as a time traveller and con man from the 51st century, who comes to travel with the Ninth Doctor (Christopher Eccleston) and his companion Rose Tyler (Billie Piper). As a consequence of his death and resurrection in the Series 1 finale, "The Parting of the Ways", Jack becomes immortal and is stranded on 19th-century Earth. There he becomes a member of Torchwood, a British organization dedicated to combating alien threats. He spends over a century waiting to reunite with the Doctor, over which time he becomes the leader of the Torchwood branch in Cardiff. He later reunites with the Tenth Doctor (David Tennant) and Thirteenth Doctor (Jodie Whittaker) for further stints on ''Doctor Who''. Aspects of the character's backstory—both prior to meeting the Doctor, and during his many decades living on Earth—are gradually revealed over ''Torchwood'' (and to a lesser extent, ''Doctor Who'') through the use of flashback scenes and expository dialogue.

Jack was the first openly non-heterosexual character in the history of televised ''Doctor Who''. The popularity of the character amongst multiple audiences directly influenced the development of the spin-off series ''Torchwood''. The character became a figure of the British public consciousness, rapidly gaining fame for actor Barrowman. As an ongoing depiction of bisexuality in mainstream British television, the character became a role model for young gay and bisexual people in the UK. Jack is featured in various ''Doctor Who'' and ''Torchwood'' books and has action figures created in his likeness. Provided by Wikipedia
